MRI background parenchymal enhancement, fibroglandular tissue, and mammographic breast density in patients with invasive lobular breast cancer on adjuvant endocrine hormonal treatment: associations with survival

Table 2 Results from the MRI and mammographic evaluation for each reader in terms of background parenchymal enhancement (BPE), fibroglandular tissue (FGT), and mammographic breast density (MD)

“n” denotes the number of observations. BPE: “A” minimal, “B” mild, “C” moderate, and “D” marked. FGT and MD: “A” fatty (< 25% of breast comprised glandular tissue), “B” scattered (25–50% of breast comprised glandular tissue), “C” heterogeneously dense (51–75% of breast comprised glandular tissue), and “D” dense (> 75% of breast comprised glandular tissue). Reader 2 and Reader 4 reported BPE and FGT of 243 and 244 patients, respectively, because they did not feel they could make a correct assessment in the change in BPE and FGT due to the presence of breast implants
